Colour Correction of Edinburgh Central Mosque Model

Nobuyuki Bannai, Alexander Agathos and I developed a method for
adjusting the colours on multiple texture maps, so that the resulting
3D models would render with consistent colouring. Nobuyuki then
applied this to a model of the Edinburgh Central Mosque. The underlying
triangulation was made by hand and then the adjusted texture maps were used.
Papers on the topic are cited below.

Before and after correction

Before correction - notice the patchwork aspect

We also explored automatic modelling using a 3D scanner. The data
was great (200 million points accurate to several mm). But it
had too many outliers (est. 1% = 2 million), which even with successful
data cleaning lest too many bad points (est. 0.01% = 20,000).
